The Future of ADCs
4
According to the research report, "Global Antibody
Drug Conjugates (ADC) Market - Analysis By Drugs
(Adcetris, Kadcyla), Pipeline Drugs, Regulations:
Opportunities and Forecasts (2017-2022)", global
market is projected to display a robust growth
represented by a Compound annual growth rate
(CAGR) of 21.82% during 2017-2022, chiefly driven
by large number of ADC drugs in pipeline, rising
number of cancer patients and wider therapeutic
window offered by antibody drug conjugates.

Case Study
• Technology transfer and optimization of bioprocess chemistry and
associated analytical methods to enable the production of antibody-drug
conjugate bulk drug substance ADC-X with 1000 gram antibody under
cGMP.
• This material will be used as an Active Pharmaceutical Ingredient for
human Phase 1 clinical trials.
• The ADC-X construct features a novel IgG1 isotype antibody conjugated
to a new drug-linker.
20
Development Strategy
• The primary goal of the development work was to deliver consistent and
scalable bioprocess chemistry that routinely affords functional ADC-X with
the desired final product specifications in high yield.
• This objective was achieved by performing evidence driven development
campaign resulting in the production of a pilot / toxicology batch, followed
by the technology transfer to cGMP production.

  • 19. 19 Case Study • Technology transfer and optimization of bioprocess chemistry and associated analytical methods to enable the production of antibody-drug conjugate bulk drug substance ADC-X with 1000 gram antibody under cGMP. • This material will be used as an Active Pharmaceutical Ingredient for human Phase 1 clinical trials. • The ADC-X construct features a novel IgG1 isotype antibody conjugated to a new drug-linker.
  • 20. 20 Development Strategy • The primary goal of the development work was to deliver consistent and scalable bioprocess chemistry that routinely affords functional ADC-X with the desired final product specifications in high yield. • This objective was achieved by performing evidence driven development campaign resulting in the production of a pilot / toxicology batch, followed by the technology transfer to cGMP production.
